Python problem: please help

Exercise 5: Plot the following functions into a single graph BUT use a subplot for each function. So your figure has 3 subplots inside. Add super title to the graph. Then for each subgraph add axes labels and a title. f(x) = ln(x) for x > 0, The derivative of f(x) that you can call g(x) = f'(x) for x > 0 and h(x) = |x|for x (-4,4)
